The 2 most common places to rust are the frame rails unnder the doors (between the "torque boxes") and the kick up over the rear end. I have seen repairs made to the side rails by welding "L" shaped lengths of steel between the torque boxes. The rear kick up is more difficult to get to.
The other side is, those frames are relativley easy to get out of there. I bought a frame from Desert Valley Auto Parts in Arizona some years ago for another '67 I had.
I guess it just depends on how "bad" the rust is.
Hope that helps.
BTW, haven't I seen your name over on the FE Forum? I don't post there much at all, but read all I can.
Oh , and Welcome to Fordmuscle!
